This is actually an incorrect assertion. Catholics believe that the Pope is infallible when speaking Ex Cathedra, or From the Seat of Peter. This means that when the Pope is speaking as the Head of the Catholic Church on Catholic Doctrine then the Pope is infallible.

The idea comes from the belief that the Pope is chosen by the Holy Spirit as St. Peter's successor.
